What Is Ice Damming And How Can I Prevent It From Happening?

Ice damming is a common issue faced by homeowners in the United States, particularly around extreme cold conditions. It occurs when snow on the roof melts and refreezes at the eaves, forming a barrier that prevents further drainage. This can lead to water seepage into the home - causing damage to walls, ceilings, insulation and even the structure itself. In the long run, it causes serious consequences.

At Salinas Exteriors, we understand the necessity of preventing ice damming to maintain the integrity of your home. In this guide, we will delve into the causes of ice damming and provide effective strategies to prevent it.

Understanding Ice Damming

1. Causes of Ice Damming

- Inadequate Attic Insulation:

Heat escaping from the attic melts the snow on your flat roof, which can then refreeze at the eaves.

- Poor Attic Ventilation:

Insufficient ventilation traps warm air in the attic, ultimately contributing to the ice dam roof.

- Fluctuating Temperatures:

Rapid temperature fluctuations can lead to snow melting during the day and refreezing at night.

- Clogged Gutters:

Debris in gutters prevents proper drainage causing water to accumulate and freeze at the eaves.

2. Consequences of Ice Damming

- Damage:

As ice dams block proper drainage, melted snow can seep into the home causing damage to ceilings, walls and insulation.

- Roof Damage:

The weight of ice freezing can strain the roof structure leading to shingle damage and leaks. In extreme cases, it could resort in your roof collapsing.

- Mold And Mildew Growth:

Moisture from water seepage could promote the growth of mold and mildew posing health risks to residents.

How To Get Rid of Ice Dams

1. Ensure Proper Attic Insulation

• Proper insulation helps maintain consistent temperatures in the attic preventing heat loss and snow melting on the roof.
• Insulate attic access doors and openings to minimize heat transfer.

2. Improve Attic Ventilation

• Install soffit and ridge vents to promote airflow and release trapped warm air from the attic.
• Consider installing attic fans to enhance ventilation, particularly in areas prone to ice damming.

3. Seal Air Leaks

• Seal gaps and cracks in the attic floor, walls and around penetrations such as pipes, vents and chimneys to prevent heat loss.
• Use caulking or weatherstripping to seal air leaks efficiently.

4. Clear Snow From The Roof

• Use a roof rake or hire professional roof contractors like Salinas Exteriors to safely remove snow from the roof after heavy snowfalls, minimizing the risk of ice dam formation.
• Exercise caution to avoid damaging shingles or injuring yourself while removing snow.

5. Clean Gutters Regularly

• Clear your gutters from debris like leaves, twigs and debris to ensure proper drainage and prevent water from backing up and freezing at the eaves.
• Install gutter guards to prevent debris buildup and reduce maintenance efforts.

6. Install Ice and Water Shield

• Try to install a waterproof membrane - such as an ice and water shield along the eaves and valleys of the roof to provide an extra layer of strength against water penetration.

7. Consider EPDM Rubber Roofing

EPDM (Ethylene Propylene Diene Monomer) rubber roofs are a durable and weather-resistant material that can be particularly effective in preventing ice damming.

Rubber roofing material eliminates vulnerable seams where water can penetrate, reducing the risk of leaks and water damage.

EPDM rubber roofing membrane is highly resistant to temperature fluctuations and UV exposure, making it ideal for cold climates prone to ice dam formation. Rolled rubber roofing can fulfill all your needs.

To conclude, ice damming can seriously cause havoc on your home causing costly damage and inconvenience.

By understanding the causes of ice damming and implementing preventive measures, you can safeguard your home against this common winter phenomenon. By adhering to these preventative measures, homeowners can minimize the risk of ice damming and protect their homes from the costly consequences associated with this winter phenomenon.
